Outboard motors are not a linear challenge.........
In 1958 my dad bought our first family boat, a 16' Botved Coronet with a single Scott Atwater 40. With my mom and pop, my three younger sisters and myslelf on board, it would indicate around 22 mph with both 6 gallon tanks full. So, having no idea what he was getting into, he bought a second Scott 40. First thing he realized was that the two 6 gallon tanks were not going to cut it so he put twin 12 gallon tanks behind the front seat and built two jump seats to cover them up. We did manage to get about 26 mph or so out of it but the real rub was that when one of the motors wasn't running (for what ever reason) he was always trying to start the motor that was already going.......... That pair of motors endured until early '61 when he chucked them both and bought a single Evinrude Starflite 75. No more twin outboards in our family.............

It certainly does seem like double trouble. For those that are wondering, he still had them as of this afternoon. They are currently short shafts but he has the kits to make them long shafts. If they were 60hp I'd be on my way to get them but at only 35hp it's a bit of not worth the effort situation.
Twice as much gas like Ray said cool looking, not much more HP as Syd said. Twice as much problems to work on twice as much money to fix problems twice as much weight, (can the boat handle the weight)? Twice as many controls to deal with, finding hens teeth to boot. Twice as much stuff to break.
I'd say find one bigger motor make it reliable and enjoy... As Jabe always says to me.. I like to keep it simple...

Jump in a boat and go
Second engine does not give a lot of extra speed, but you have the extra power for a bigger load and if ones gives you trouble you still have one to get back on. My dad got a 76 starcraft fishung boat and put a pair of 18's on it..after the first start of the day I could set the throttles and walk back and grab a starter cord in each hand and give a quick short pull and they both would start up. Thought that was the coolest thing.
Ok before I do something silly, what do you think of these twin 35s on the back if the clipper? Merky I know what you will say But are two 35s enough power? I know they will look cool but will it move?
